U-Boot loader for BeagleBone and BeagleBone Black.
This version is patched so that:
* ELF and API features are enabled
* U-Boot binary is called BB-UBOOT.IMG
* It loads env from BB-UENV.TXT (an empty file suffices)
* It loads BBONE.DTB if running on an older (white) BeagleBone,
or BBONEBLK.DTB if running on a BeagleBone Black
* By default, it loads ELF ubldr from file BBUBLDR to address 0x88000000
Note: prefixing the boot files with 'BB' allows building
images with boot bits for more than one board.

Remove unstaged devel/arm-eabi-gcc and cascade remove four others
Without devel/arm-eabi-gcc, unstaged cross-gcc has no purpose, nor
does either of the -binutils ports. The sysutils/u-boot-beaglebone-eabi
was staged, but is a casualty of the arm-eabi-gcc removal.
